Studies in developed countries have revealed an association of different magnitudes between watching television and the risk of being overweight and obese among reproductive age women. Even so, there is no evidence of such an association in the context of the Ethiopian population. Hence, the study aimed to assess the association between watching television with overweight and obesity in a nationally representative sample of Ethiopian women.
A cross-sectional study was conducted by using secondary data analysis from 2016 Ethiopia demographic and health survey among women aged from 15 to 49 years. The samples were selected using a two-stage stratified cluster sampling technique. A total of 10,074 women were included in the analysis. The outcome variables were both overweight and obesity, whereas the main exposure variable was the frequency of watching television. Multivariate logistic regression analysis was performed for adjusting potential confounders. Adjusted odds ratio (AOR) with 95% confidence intervals was used to declare a statistically significant association.
The study found that watching television at least once a week was significantly associated with both overweight (AOR: 1.79; 95% CI: 1.20-2.73) and obesity (AOR: 3.76; 95% CI: 2.04-6.95). The study also divulged that the odds of overweight were higher among women aged 25-39 years (AOR: 2.17; 95% CI: 1.25-3.77) and 40-49 years (AOR: 2.69; 95% CI: 1.45-5.00), urban residents (AOR: 1.76; 95% CI:1.17-2.65), attended higher education (AOR:2.11; 95% CI: 1.22-3.65), and richest in the wealth index (AOR: 2.83; 95% CI:1.71-4.68). Similarly, the odds of obesity were higher among women aged 25-39 years and 40-49 years, attended higher education, and the richest in wealth index.
The results from this study demonstrated that watching television at least once a week is associated with obesity among reproductive age women in Ethiopia. Therefore, a social behavioral change communication campaign needs to be taken to improve awareness regarding the harmful consequences of watching television for long hours. Further research studies should be conducted among men and adolescents to determine whether this positive association exists among that target population as well.
发达国家的研究表明，看电视的时间与育龄妇女超重和肥胖的风险之间存在不同程度的关联。即便如此，在埃塞俄比亚人群中，还没有证据表明存在这种关联。因此，本研究旨在评估在埃塞俄比亚全国代表性妇女样本中，看电视与超重和肥胖之间的关联。
本研究使用了 2016 年埃塞俄比亚人口与健康调查中 15 至 49 岁妇女的二次数据分析进行横断面研究。采用两阶段分层聚类抽样技术选取样本。共纳入 10074 名妇女进行分析。因变量为超重和肥胖，主要暴露变量为看电视的频率。采用多变量逻辑回归分析调整潜在混杂因素。采用调整后的优势比（AOR）及其 95%置信区间来判断统计学显著关联。
研究发现，每周至少看一次电视与超重（AOR：1.79；95%CI：1.20-2.73）和肥胖（AOR：3.76；95%CI：2.04-6.95）均显著相关。研究还表明，25-39 岁（AOR：2.17；95%CI：1.25-3.77）和 40-49 岁（AOR：2.69；95%CI：1.45-5.00）、城市居民（AOR：1.76；95%CI：1.17-2.65）、接受过高等教育（AOR：2.11；95%CI：1.22-3.65）和最富裕的财富指数（AOR：2.83；95%CI：1.71-4.68）的女性超重的几率更高。同样，25-39 岁和 40-49 岁、接受过高等教育和最富裕的财富指数的女性肥胖的几率更高。
本研究结果表明，每周至少看一次电视与埃塞俄比亚育龄妇女肥胖有关。因此，需要开展社会行为改变传播运动，提高人们对长时间看电视的有害后果的认识。还应在男性和青少年中开展进一步的研究，以确定这一正相关是否也存在于该目标人群中。
